1. New continental margin magnetic anomalies of East Antarctica

   Over the past decade, Australian, Norwegian and Russian marine surveys have collected integrated seismic, gravity and magnetic data in the southern Indian Ocean. The more than 350,000 line-km of new […]

2. Inland extent of the Weddell Sea Rift imaged by new aerogeophysical data

   The Weddell Sea Rift was a major focus for Jurassic extension and magmatism during the early stages of Gondwana break-up and underlies the Weddell Sea Embayment, which separates East Antarctica […]

3. Analysis of James Ross Island volcanic complex and sedimentary basin based on high-resolution aeromagnetic data

   High-resolution aeromagnetic surveys provide a geophysical tool to help image the subsurface structure of volcanoes and their tectonic framework. Here we interpret high-resolution aeromagnetic data and models for James Ross […]

4. Magnetic susceptibilities of rocks of the Antarctic Peninsula: Implications for the redox state of the batholith and the extent of metamorphic zones

   A combination of 1555 magnetic susceptibility measurements from the Antarctic Peninsula between 65°S to 72°S (for which the raw data are made available), and petrological, structural and metamorphic data, has […]

5. Air and shipborne magnetic surveys of the Antarctic into the 21st century

   The Antarctic geomagnetics’ community remains very active in crustal anomaly mapping. More than 1.5 million line-km of new air- and shipborne data have been acquired over the past decade by […]

7. Sensitivity analysis identifies high influence sites for estimates of penguin krill consumption on the Antarctic Peninsula

   Krill consumption by natural predators represents a critical link between surveys and models of standing krill biomass and the design of a sustainable krill fishery for the Scotia Sea. Antarctic […]

8. A new 100-m Digital Elevation Model of the Antarctic Peninsula derived from ASTER Global DEM: methods and accuracy assessment

   A high resolution surface topography Digital Elevation Model (DEM) is required to underpin studies of the complex glacier system on the Antarctic Peninsula. A complete DEM with better than 200m […]

9. Changes in distribution, relative abundance, and species composition of large whales around South Georgia from opportunistic sightings: 1992 to 2011

   To examine the general population trends of large whales in South Georgia waters, 2 opportunistic data sets of sightings of large whales from 1991 to 2010 around South Georgia were […]

10. A compilation of parameters for a krill-fishery predator model of the Scotia Sea and Antarctic Peninsula (working paper version)

    We describe the compilation and derivation of parameters for use in krill-fishery-predator models of the Scotia Sea – Antarctic Peninsula region. The primary aim is to provide input for the […]

11. Reference observations for validating and tuning operating models for krill fishery management in Area 48

    In 2007 WG-SAM defined a set of reference observations for validating and tuning proposed models to evaluate krill catch allocation options for Area 48 (the SAM calendar). The observations, which […]

12. Prospects for a sustainable increase in the availability of long chain omega 3s: lessons from the Antarctic krill fishery.

    • The global summit on nutrition, health and human behaviour (GSNHHB) identified the objective of increasing “the availability of long chain Omega‐3 (especially docosahexaenoic acid) for human consumption in a […]
